Non of them hit like Hendricks... we have seen GSP wobbled before remember!

GSP fights better against heavy hitters because they either plant their feet and/or come barging in and that makes them an easy target for the takedown. Hardy, Condit, Serra (2nd time round), BJ Penn (in some respects) and Alves all have KO ability in both hands... Yet none of them could finish him.

**Please note, I said Serra the second time round, since his loss in their first fight hes never really looked like losing a fight (bar the minute of madness in the condit fight.

Ellenberger and Hendricks have the best shot as both are good wrestlers with KO power. As stated earlier I don't see either of them winning a decision, but they are both very capable of turning GSP's lights out. I think the main benefit of their wrestling credentials is the ability to keep the fight standing longer to land that shot.
